But the 29-year-old remains hopeful of joining Jose Mourinho’s squad this week as they prepare for their pre-season tour.

United flew to Los Angeles on Sunday and Sanchez was a notable absentee, after training last week with team-mates at their Carrington base.

Another player not on the tour is defender Daley Blind, for whom Ajax have made a £15.8 million bid that United accepted on Monday night.

United open their pre-season campaign against Mexican side Club America on Friday.

Last season’s FA Cup finalists then face Major League Soccer side San Jose Earthquakes, AC Milan, Liverpool and Real Madrid – the last three as part of the annual International Champions Cup tournament.
